The Uplink BER Performance of MC-CDMA with Frequency-domain Pre-equalization Transmit Diversity

چکیده
Abstract Recently, multi-carrier code division multiple access (MC-CDMA) has been attracting much attention for the broadband wireless access in the next generation mobile communications systems. In the case of uplink transmissions, the orthogonality among users’ signals is destroyed since each user’s signal goes through different fading channel and hence, the use of frequency-domain pre-equalization at the receiver cannot sufficiently improve the up-link transmission performance. In this paper, we propose frequency-domain pre-equalization transmit diversity and evaluate the BER performance improvement by computer simulation.

متن کاملFrequency Domain Transmit Equalization for Uplink MC-CDMA
Abstract In multi carrier code division multiple access (MC-CDMA), since signals transmitted from different users go through different frequency-selective fading channels, the use of frequency-domain equalization at a receiver can only partially restore the orthogonality property among different users’ signals, resulting in the degraded bit error ratio (BER) performance due to large multi-acces...
متن کاملFrequency-Domain Pre-Equalization for MC-CDMA/TDD Uplink and Its Bit Error Rate Analysis
In multi-carrier code division multiple access (MCCDMA) uplink (mobile-to-base station), since different users’ signals go through different frequency-selective fading channels, large multi-access interference (MAI) is produced. The use of frequency-domain equalization reception can only partially restore the orthogonality among different users’ signals, resulting in a severe degradation in the...
متن کاملPerformance Improvement with Space-Time Transmit Diversity using Minimum Mean Square Error Combining Equalization in MC-CDMA
Abstract In this paper, the space time transmit diversity (STTD) decoding combined with minimum mean square error combining (MMSEC) equalization is presented for MC-CDMA. The STTD decoding weights that minimize the MSE for each subcarrier before despreading are derived. From computer simulation, it is found that the BER performance of STTD with MMSEC equalization using the weights derived in th...
